  • Method of removing arsenic from a liquid
    Patent number: 11053138
    Abstract: A method for removing arsenic from a liquid includes adding a two-dimensional metal carbide adsorbent to the liquid to adsorb the arsenic from the liquid. The two-dimensional metal carbide adsorbent can include at least one MXene, having the formula Mn+1Xn, where n=1, 2 or 3, where M is an early transition metal, such as scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo) or the like, and X is either carbon or nitrogen. The MXene may be Ti3C2.
    Type: Grant

  • Method of removing barium from a liquid
    Patent number: 10933399
    Abstract: A method of removing barium from a liquid includes adding a two-dimensional metal carbide water contaminant adsorbent to water to adsorb contaminants, such as barium (II), from the liquid. The two-dimensional metal carbide water contaminant adsorbent is in the form of at least one MXene, having the formula Mn+1Xn, where n=1, 2 or 3, M is an early transition metal, such as scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo) or the like, and X is either carbon or nitrogen. The MXene may be Ti3C2. The liquid may be, for example, at least one water by-product from at least one oilfield reservoir, such as produced water, co-produced water or a combination thereof.

  • METHOD FOR ADSORPTION OF TOXIC CONTAMINANTS FROM WATER
    Publication number: 20190352196
    Abstract: The present disclosure provides an iron-modified montmorillonite adsorbent for effectively removing heavy metals from water. The iron modified montmorillonite can be synthesized using a facile intercalation wet synthesis procedure that requires low energy and minimal use of chemicals. The iron modified montmorillonite adsorbent effectively removes heavy metals, such as arsenite, strontium, barium, phosphate, from water.
